Founding member of the JSA, its original leader, and one of the big three. He's sort of a father figure to all the younger members as someone who, even though he's old, keeps running.

The best boxer in the DCU and one of the big three of the JSA. One of Batman's fighting teachers and an inspiration for new generations of superheroes.

One of the founding members of the JSA and one of the big three. His two children were members of the Infinity, Inc. offshoot team, and Obsidian is a current member of the JSA. He's been there from day one, and he's always on the front lines, even when people like Jay Garrick can't be there. He has ties to the Green Lantern Corps, Checkmate, and almost everyone else. He's the ultimate father figure of the JSA with the ultimate legacy.

The perfect example of one of the kids of the JSA all grown up. The cousin of Superman from an alternate universe and the JSA's current leader. Super strong and super feminist, despite her not so feminist of clothing.

One of the JSA's greatest leaders and one of the smartest men in the world. Also a legacy hero, the specialty of the JSA, as the second Mr. Terrific.
